Platforms · Signaling & CDR Intelligence An end-to-end platform that captures signalling across SS7, SIGTRAN and SIP / VoIP, correlates it with CDRs, and turns the result into live dashboards, anomaly alerts, and evidence-ready packages with full chain of custody. Read-only, passive, and vendor-independent — zero impact on live traffic.

Four reasons revenue, fraud, and legal teams put their own capture-and-correlation platform on the network — even where vendor reporting exists. 01 · PASSIVE ### Zero impact on live traffic. Read-only at the wire. Probes and mirror ports. No inline processing. The capture layer is invisible to the call path — operationally and operationally-safely. 0 Inline footprint 02 · VENDOR-AGNOSTIC ### Every vendor in one canonical model. Pre-built parsers for every major switch and mediation vendor. Custom parsers added during discovery. Every record converges into one canonical schema before correlation. 1 Canonical model 03 · CORRELATED ### Signalling and CDR in one timeline. SIP ingress, SS7 routing, ISUP setup, M3UA transport, CDR landing — every transaction replayed end-to-end. ASR / QoS dips drill into the signalling event that caused them. End-to-end Replay 04 · COURT-READY ### Chain-of-custody as a built-in export. Structured exports with documented integrity and expert-witness-grade technical explanations. Regulatory and legal requests addressed inside hours, not weeks. Sealed Evidence packs Protocol coverage ## SS7. SIGTRAN. SIP. One capture layer. Generations of telecom transport, captured passively and decoded in one place. Pre-built parsers for major switch vendors mean integration does not start at protocol primer. ### SS7 stack Classic signalling, fully decoded — MTP2 / MTP3 transport, ISUP for circuit-switched voice, SCCP for routing, TCAP for transactions, MAP for mobile services, CAP and INAP for intelligent network. MTP2 MTP3 ISUP SCCP TCAP MAP CAP INAP ### SIGTRAN over SCTP All four SIGTRAN adaptations carried over SCTP: M2PA, M2UA, M3UA and SUA. Direct integration with modern core networks running SS7-over-IP transport. M2PA M2UA M3UA SUA SCTP ### SIP · VoIP RFC 3261 compliant capture — all methods, all headers. SBC logs, softswitch interfaces, SIP-trunk monitoring. Full call-flow visibility ingress to egress. RFC 3261 INVITE REGISTER BYE OPTIONS all headers ASR · QoS monitoring ## Answer-Seizure Ratio, at every level of the network. ASR by route, trunk, time-of-day, destination. Baseline established per slice, deviation flagged proactively. Root-cause analysis correlates degradation with signalling-layer events — operators see _why_ a route is failing, not just that it is. - **Multi-dimensional baselines** — per route, trunk, destination, time of day, day of week. - **Real-time deviation alerts** — proactive notification when KPIs drift outside the baseline envelope. - **Signalling-driven root cause** — drill from a KPI dip into the signalling events that caused it. - **Capacity planning** — historical trends fuel forward-looking projection of switch and trunk load.

Retention tiers ## From operations to regulatory vault. Storage tiered by access pattern and retention requirement. Cold tiers run at 10:1 compression; vault tier ships with chain-of-custody seals for regulator and law-enforcement requests. Hot 30d Most recent traffic, query in seconds, optimised for live dashboards and ad-hoc forensics. Warm 90d Reconciliation and trend analysis, query in tens of seconds, full-resolution records. Cold 2y Archive for compliance and dispute review, compressed 10:1, query in minutes. Vault 7y+ Long-term retention for regulatory and legal mandates, sealed with chain-of-custody. Pre-built parsers ### Integration does not start at protocol primer. Parsers exist for the switch and mediation kit you already run, from every major network-equipment provider. Custom parsers for proprietary formats are scoped during the discovery phase. Major NEP A Major NEP B Major NEP C Major NEP D Use cases ## One platform. Three teams that fight different fires. ### Revenue Assurance Multi-point reconciliation across switch → mediation → billing → partner. Leakage detection by route and trunk. Margin verification on retail vs wholesale. ### Fraud & Security Abnormal-pattern detection on signalling and CDR. Velocity checks, suspicious destination distributions, IRSF and bypass-fraud signatures. ### Legal & Compliance Court-ready evidence packages with chain-of-custody, structured CSV / XLSX exports, expert-witness-grade technical explanations. Regulator response in hours, not weeks. Illustrative operator scenarios ## What a court-ready intelligence layer changes. Tier-1 GCC operator Telecom · Gulf AE **Challenge** A long-running interconnect dispute lacked attributable evidence; partner billing showed completed calls the operator's own systems did not record. **Approach** Passive SS7 / SIGTRAN capture replayed end-to-end transactions and signalling-to-CDR correlation matched each disputed call across switch, trunk, and mediation. Revenue assurance lead End-to-end Transaction replay Chain-of-custody Evidence MENA carrier group Telecom · Levant LB **Challenge** ASR degradation on one international trunk was visible in the NOC dashboard but root cause was hard to attribute and operations was chasing the wrong layer. **Approach** Signalling-driven drill-down from the ASR dip surfaced an M3UA routing miss correlated with the failed calls; capacity planning identified a sustained trend. NOC team lead Signalling root Attribution Re-usable Correlation template Pan-African operator Telecom · Sub-Saharan NG **Challenge** A regulator inquiry requested signalling and CDR evidence for a multi-week window covering several trunks, and the existing reporting tools could not assemble it. **Approach** The vault retention tier was queried for the time-range; signalling and CDR were correlated and packaged with chain-of-custody documentation.

Learn more](https://www.broadnet.me/platforms/performance-system) Questions buyers ask ## Eight questions NOC, RA, and legal ask. Zero. The platform is read-only and passively monitored — traffic is captured through probes, mirror ports, signalling-gateway interfaces, SBC and softswitch logs. Nothing is inline. No processing in the call path. No modification of any message. Pre-built parsers exist for every major network-equipment provider. Custom parsers for proprietary formats are scoped during the discovery phase and added to the canonical-model mapping. Whatever the source format, every record converges into a single canonical schema before correlation. Full SS7 — MTP2, MTP3, ISUP, SCCP, TCAP, MAP, CAP, INAP. Full SIGTRAN over SCTP — M2PA, M2UA, M3UA, SUA. Full SIP / VoIP per RFC 3261 — all methods, all headers, SBC and softswitch capture. One platform, every generation of telecom signalling that touches the network. Signalling messages and CDRs share keys — call-id, trunk-id, timestamps, party identifiers. The correlation engine matches them in real-time and on-replay, so a single transaction can be replayed end-to-end: SIP ingress through SS7 routing through CDR landing in billing. The result is a complete story per transaction, not isolated layer-by-layer views. Structured data exports (CSV / XLSX) with all relevant fields, chain-of-custody documentation proving data integrity from capture to export, and an expert-witness-grade technical explanation suitable for legal proceedings. Packages are sealed with cryptographic checksums and tamper-evident logging. Four tiers: hot (typically 30 days, query in seconds), warm (typically 90 days, full resolution for reconciliation), cold (typically two years, 10:1 compression, query in minutes), and vault (7+ years with chain-of-custody for regulatory and legal mandates). Tier durations are configured per operator policy and storage budget. Switch-vendor reports show what the switch sees. The Signaling & CDR Intelligence System correlates across switches, trunks, mediation, billing and signalling-layer events from passive capture — it is the independent verification layer. It catches the discrepancies that single-vendor reports cannot, because no single vendor sees the whole network. A typical engagement runs in three phases: discovery and source mapping, pilot deployment against a defined slice of traffic, then full rollout. Operator infrastructure complexity drives the timeline — most operators are in production-grade pilot inside a quarter and fully rolled out shortly after. Question not here?
